Heavy crude is less in demand than light crude, because it needs more expensive refining to make it usable. Since it is less in demand, it is cheaper to buy.
light crude oil has less specific gravity,less viscosity while heavy crude oil has more specific gravity & viscosity.
boiling point of crude oil is depending on the main component in the crude oil itself, heavy crude for example has a higher boiling point from light crude.
Crude oil is oil as it comes out of the ground. it generally contains many different weights of oil compounds, sulphur, water and sediment. Crude ranges from heavy (lots of long chain molecules) to light (short chains) and sour (lots of sulphur) to sweet (little sulphur). Artificial crude many be made from very heavy oils or recovered from the liquids associated with natural gas production.
The properties of Brent Crude oil are the same properties of any crude oil, density, viscosity, and solubility. Although Brent is LCO (light crude oil).
Brent Crude is a light oil and is classified as a sweet crude. It contains 0.37% sulfur, has an API gravity of 38.06, and a specific gravity of .835.
light crude oil has less specific gravity,less viscosity while heavy crude oil has more specific gravity & viscosity.
boiling point of crude oil is depending on the main component in the crude oil itself, heavy crude for example has a higher boiling point from light crude.
A barrel of oil contains 42 gallons. A gallon of light crude oil weighs approximately 7.27 pounds. Heavy crude oil weighs 7.61 pounds per gallon. Therefore a barrel of light crude oil weighs 305.34 pounds + the weight of the barrel. Heavy crude would weigh 319.62 pounds + the weight of the barrel.
Specific gravity of crude oil is how light or heavy it is compared to water. If the API gravity is less than 10 it will float in water.
Crude oil is a very complex mixture of hydrocarbon compounds with some inorganic compounds. Simple quality terms (light/ heavy and sour/ sweet) are defined for convenience and are inadequate terms to fully characterize the crude. However, as discussed in the links, a crude that has less than 0.5% sulfur content is sweet crude. Oil that is between 37 to 42 degrees API in density is light oil. Other definitions exist (see link), however this appears the range used for US produced crude. Light sweet crude will sell for higher prices than other grades, (Heavy sour, heavy sweet, light sour). Many countries produce light sweet crude including Russia, Saudi Arabia, Iraq, Brazil, Angola, Nigeria, and the US. Please see related links.

There is extra-light, light, light-medium, medium, medium-heavy, heavy, extra-heavy. There is sweet and there is sour. There is paraffinic, paraffinic-naphthenic, naphthenic, aromatic-intermediate, aromatic-naphthenic, aromatic-asphaltic.
Easy answer you could have come up with by yourself I think. Crude oil, means oil straight from the ground and not refined yet. Heavy metals means not light metals. So not iron or sodium but Lead and other heavy stuff. Since oil comes from the ground and metals are mined from the ground, it makes sense that they could be found together. So if the teacher wants a different answer he should have said "how is crude oil formed" or something like that.
BLCO means "Bonny Light crude oil" which is a crude from Nigeria.

viscosity. very viscose oils are considered "heavy", oils of low viscosity are considered "light". Oils with little sulfur are considered "sweet", oils with lots of sulfur are considered "sour". The most valuable crude oil is "light sweet".
Both. Mexico produces three types of oil with varying degrees of viscosity.
